OPI

Allows you to check the document for the use of OPI information.

Open Prepress Interface (OPI) allows you to use only low-resolution images in your documents during the design process. Using OPI, these low-resolution images are automatically replaced with high-reso­lution images when the separations are printed for the documents. If you use OPI to work with files containing only small, low-resolution images in your page lay-out applications (e.g. Adobe InDesign), you can reduce the processing time when you are working with the files.

If PitStop detects OPI information in your document, the document:

• May contain the high-resolution images, in which case the OPI links are no longer useful, and were probably included accidentally.
• May have been created with low-resolution images, in which case the high-resolution images were either accidentally omitted, or the document was created in an OPI work­flow, which is not allowed by your Preflight Profile or Action List.

Possible fixes

You can remove all OPI information from the document.
